From 8a39374ef8b849dfd18e7d8dd52ef8ffee0f1042 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Tue, 11 Jul 2017 16:33:13 +0200 Subject: [PATCH] drm/atomic: Add __must_check to drm_atomic_helper_swap_state. Now that all drivers check the return value, convert swap_state to __must_check. This is done separately to force build warnings if we missed a driver.
